Walker Products 250-24414 oxygen sensor for the 2000-2005 Volkswagen Passat V6 2.8L and other vehicles measures combustion efficiency from the oxygen in the exhaust gas. This Walker Products oxygen sensor is a 4-wire, narrow-band, direct-fit design.
- Electrodes made of a gas-permeable platinum layer
- Measures oxygen levels to fine-tune the air-fuel mixture and support fuel economy
- Monitors exhaust gases and the air-fuel ratio to help reduce pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Built for one application and fitment position, returning the diagnostic feedback the ECU expects
Quick facts
- Part: Walker Products 250-24414 oxygen sensor
- Fits: the 2000-2005 Volkswagen Passat V6 2.8L and other vehicles
- Position: downstream left, downstream right, downstream front, downstream rear
- Condition: New
A failing oxygen sensor can show up as rough running, higher fuel use or a lit check engine light, and stored fault codes may relate to the sensor. Before you replace the sensor, rule out physical damage to its wiring harness and connector, which you can see with the engine off and cool; damage there can shorten a sensor's life too.
Fits
The 2000-2005 Volkswagen Passat V6 2.8L, the 2000-2001 Audi A6 Quattro V6 2.7L or 2.8L, the 2000-2004 A6 Quattro V8 4.2L and the 2003-2004 Audi RS6 V8 4.2L all fit this sensor, and so do many other vehicles. If your car is not named here, check its year and engine in the "Vehicles it fits" section. This listing is one sensor, and each downstream position on the car takes one.

Frequently Asked Questions
Is this the right VW Passat O2 sensor for a 2000-2005 model with the V6 2.8L?
Yes. Walker Products 250-24414 is a Passat oxygen sensor for the 2000-2005 model with the V6 2.8L.
Is this an Audi A6 Quattro oxygen sensor for a 2000-2004 model with the V8 4.2L?
Yes. Walker Products 250-24414 fits the 2000-2004 Audi A6 Quattro V8 4.2L, and also the 2000-2001 A6 Quattro V6 2.7L or 2.8L.
Is the Walker Products 250-24414 a narrow-band sensor?
Yes. Walker Products 250-24414 is a narrow-band, direct-fit oxygen sensor with 4 wires.
Can a bad oxygen sensor raise fuel use or turn on the check engine light?
Yes. A failed oxygen sensor can make the engine run poorly, raise fuel consumption and exhaust emissions, or light the malfunction indicator lamp, and a shop can read the stored fault codes.
What are the electrodes in the Walker Products 250-24414 made of?
The Walker Products 250-24414 has electrodes made of a gas-permeable platinum layer. A coating protects the electrode surfaces from combustion residue and particulates in the exhaust.
